Taking into account all the factors , such as sensor type and application conditions , you should follow the recommended calibration method :According to the operator 's judgment, the gas sensor is surrounded by the fresh gas , no abnormal condition exists , this time , the meter indicates near zero (reading ) , the zero setting procedure can be skipped. When in doubt , use a plastic bag around Engine Coolant Temp Sensor to get some considered to be " fresh " air. This is a very quick and easy process . This method for the difference between true and false alarm warning is very effective . There is an advantage that the compressed air , the gas in the bottle is easy to control and easy to carry . The device is easy and convenient to get air . Such a small amount of air in the meaning of hydrogen and nitrogen , carbon monoxide , carbon dioxide and some other interfering gases . However , this gas is characterized by low humidity , the solution used in the sampling system with activated carbon filters are used to filter out unwanted wet gas in the gas and water vapor. After this process , we can use the gas for various types of Ect Engine Coolant Temperature Sensor calibration . However, it should be noted that carbon monoxide gas and not through a filter with activated carbon and filtered . Therefore, the rule states: cylinders of carbon monoxide gas with the surrounding environment must be the same content . In addition , the use of soda ash filter can filter out carbon monoxide. Since the sampling system using soda ash pipeline filters can filter out carbon monoxide, carbon dioxide sensor so this method is a good way for zero setting , it is easy to obtain basic 0:00 . Although synthetic gas is usually very pure , but it is not used solid-state sensors and photoionization detectors, because such sensors require the gas sample contains some water vapor. A simple way to solve this problem is to use the sampling system pipeline damp tissue paper . Its role is to make the wet stream sample , the sensor has sufficient water vapor. Another option of using NAFION tube .
